undefined symbol: apr_reslist_maintain after upgrading httpd on Slackware 13.37

After upgrading apache to the latest patch (ftp://ftp.slackware.com/pub/slackware/slackware-13.37/patches/packages/) you get that error: "/usr/sbin/httpd: symbol lookup error: /usr/sbin/httpd: undefined symbol: apr_reslist_maintain" when starting httpd / apache.

In order to resolve it you have to update apr (Apache Portable Runtime, makes sense, huh? ;)) and apr-util to the latest patched versions (get them here ftp://ftp.slackware.com/pub/slackware/slackware-13.37/patches/packages/).

"QGtkStyle was unable to detect the current GTK+ theme." [SOLVED]

Finally found the solution:

Show single image with xlock

Took me a while to figure out how to simply show an image when locking with xlock:

$ xlock -mode image -bitmap image.xpm -count 1

-mode image: sets the mode to only display random sun images
-bitmap image.xpm: replace the random sun images with image.xpm (*)
-count 1: sets the amount of images that shall be shown at the screen at once to 1

* use ImageMagicks 'convert' method to convert to xpm: $ convert input.jpg output.xpm

Have fun!

x121e Cardreader (rtl_pstor) - Kernel 3.4.4 menuconfig

Took me a while to figure out where the driver for my cardreader resides. In menuconfig go this path:

Device Drivers -> Staging drivers

and check this one, either as module or builtin:

No longer Skype beta on Linux - Skype 4.0!

Skype 4.0 has been released.
Of course, there's no Slackware-Package available from the Skype homepage. (Who knew? ;))

If you want to upgrade to Skype 4.0 today, you can use this Source-Package:
http://download.skype.com/linux/skype-4.0.0.7.tar.bz2

and build it by using this SlackBuild:
https://github.com/willysr/SlackHacks/tree/master/SlackBuild

The SlackBuild script linked above has also been submitted to slackbuilds.org, but currently it's in the pending queue (and I've seen script in the pending queue for about two months, so don't count on that :)).

NOTE: If you're on a 64 bit Slackware you need to add 32 bit librarys. See this page for further information: http://www.linuxquestions.org/questions/slackware-14/skype-4-0-on-slackware-13-37-64bit-4175411533/

Have fun... well, you have fun, I mean, you're using Slackware. :)

Edit: Ahh, finally there's a fresh, warm, approved Slackbuild available.

Automated slackware package creation from given sourcefile

Slackware packages are a great (the only good way) to keep track of the installed software on (and to cleanly remove installed software from) your slackware machine.

Most packages that you can find in the www (slackbuilds.org, http://packages.slackware.it, ...) are outdated. You know that: Looking at slackbuilds.org for a tool, then looking at the version number and see that there's a source on the builders homepage that's x major and y minor releases further.

I, personally, hate to install 'old' software. I want the newest. So I have to built from source - make, ./configure --flags, make install to a DESTDIR, cp docs, change rights and makepkg at the end.

This sucks. To learn a bit about writing shellscripts I started to write a shellscript that does the job (yes, I know about pkgbuild). Currently it's able to:

• remove old sources
• remove old package
• extract the source package (tar.gz / tar.bz2)
• copy a given layout file (supported by apache httpd for instance)
• make install to DESTDIR
• create documentation directory
• copy documentation files (like README, INSTALL, AUTHORS...)
• chown root.root DESTDIR
• build package with makepkg
• echo build time

 And here is what I plan to add:

• remove sources after successful build
• remove installation from DESTDIR after successful build
• automatically search SRCDIR for documentation and copy it
• really important: create slack_desc for created package
• really important: output last 5 rows if build fails
• really important: check for $DESTDIR support
• make it much cleaner
• less params

Yesterday I built the whole xfce4 from source in approx 15 minutes. Added install.sh to installpkg the packages in the right order and et voilà - installed xfce4 in 30 seconds. :-)
